The side box portion is provided with a side support block for side support of the floor mopping machine. The side support block defines a groove for receiving the handle of the floor mopping machine. An electrical connection device can be arranged in the groove. After the electrical connection device and the handle are conducted, users can control the water pump through a button on the handle.

The working principle of the cleaning dock capable of replenishing the floor mopping machine is as follows.

When the floor mopping machine 52 is used to clean a ground, the rotation driving device 527 rotates the rag 523 of the floor mopping machine to wipe and clean the ground. The floor mopping machine 52 can control the operation of the water pump of the floor mopping machine through a corresponding button. The water pump of the floor mopping machine can pump the liquid from the water tank 521 of the floor mopping machine. The liquid is pumped to the spray head 526 through the first cleaning valve port 5291 and the second cleaning valve port 5292 in sequence, and the liquid is sprayed onto the ground to be cleaned through the spray head 526.

After the floor mopping machine 52 has been used, it is placed on the dock body 51. When the charging plug 524 is plugged into the charging socket 514 and both are in an energized state, it is deemed that the floor mopping machine 52 has been installed in place. That is, the cleaning plug nozzle 551 is plugged into the third cleaning valve port 5293 in a sealing and communicating manner. In addition, the water replenishment plug nozzle 552 has been plugged into the second replenishment valve port 5282 in a sealed and communicating manner.

At this time, the third cleaning valve port 5293 and the first cleaning valve port 5291 are in a communicating state. The second cleaning valve port 5292 and the first cleaning valve port 5291 are in a non-communicating state. And, the first water replenishment valve port 5281 and the second water replenishment valve port 5282 are in a communicating state.

During this period, the battery in the floor mopping machine 52 is continuously charged, and the water level sensor detects the liquid level in the water tank 521 of the floor mopping machine.

When the water level is below a max value, the replenishment pump 53 starts to operate. The replenishment pump 53 pumps the liquid from the replenishment tank 512 to the water tank 521 of the floor mopping machine through the water replenishment flow path 5520, the water replenishment plug nozzle 552, and the water replenishment valve body 5251 in sequence, until the water level in the water tank 521 of the floor mopping machine is not lower than the max value.

When the water level is not below the max value, the water replenishment pump 53 does not operate, that is, only the battery in the floor mopping machine 52 is charged.

When the rag 523 of the floor mopping machine needs to be cleaned, the corresponding button on the floor mopping machine 52 is pressed. At this time, the rotation driving device 527 drives the rag 523 of the floor mopping machine to rotate and rub on the cleaning plate 54. At the same time, the water pump of the floor mopping machine pumps the liquid from the water tank 521 of the floor mopping machine. The liquid sequentially passes through the first cleaning valve port 5291, the third cleaning valve port 5293, the cleaning plug nozzle 551, the cleaning flow path 5510, and the nozzle 542, and is sprayed onto the cleaning plate 54 for wetting the rag 523 of the floor mopping machine. The rag 523 of the floor mopping machine obtains a cleaning effect under the water friction washing by the cleaning ribs 541. The sewage flowing down from the cleaning plate 54 is led to the sewage cleaning tank 513 for being cleaned up afterwards.

The cleaning water is pumped into the spray head 826, and the cleaning water is sprayed onto the ground to be cleaned through the spray head 826.

After the floor mopping machine 82 has been used, it is placed on the cleaning dock 81. At the same time, the water replenishment plug nozzle 85 is plugged into the second valve port 8252 in a sealed and communicating manner. At this time, the first valve port 8251 and the second valve port 8252 are in a communicating state.

Subsequently, a water level sensor arranged on the water tank 821 of the floor mopping machine detects the cleaning water level in the water tank 821 of the floor mopping machine. When the water level is below a max value, the water pump 83 starts to work and the solenoid check valve 8331 for water replenishment is turned on. The water pump 83 pumps the cleaning water from the water tank structure into the water tank 821 of the floor mopping machine sequentially through the water inlet pipe 831, the water outlet pipe 832, the branching tee 8320, the water replenishment pipe 833, the water replenishment channel 850, the water replenishment plug nozzle 85 and the water replenishment valve 825. After the water level in the water tank 821 of the floor mopping machine is not lower than the max value, the water pump 83 stops working and the solenoid check valve 8331 for water replenishment is in a shut-off state. When the water level is not below the max value, the solenoid check valve 8331 for water replenishment is in a shut-off state, and the water replenishment pump 83 is not in operation.

When the rag 823 of the floor mopping machine needs to be cleaned, a corresponding button on the floor mopping machine 82 is pressed. At this time, the rotation driving device 827 drives the rag 823 of the floor mopping machine to rotate and rub on the cleaning plate 84. The operation of the water pump 83 is started, and the cleaning solenoid check valve 8332 is turned on. The water pump 83 pumps the cleaning water from the water tank structure to the cleaning plate 84 so as to wet the rag 823 of the floor mopping machine, sequentially through the water inlet pipe 831, the water outlet pipe 832, the branching tee 8320, the cleaning pipeline 834, the cleaning flow path 8420 and the nozzle 842. The rag 823 of the floor mopping machine obtains a cleaning effect under the water friction washing of the cleaning rib 841.
